ChatGPT Health fails to direct 52% of medical emergencies to emergency care in study
A study published in Nature Medicine found that OpenAI's ChatGPT Health tool under-triaged 52% of true medical emergencies, directing users to non-urgent care instead of emergency departments. The AI also misclassified 35% of non-urgent cases. Researchers at Mount Sinai conducted 960 tests across 60 clinical scenarios, noting the tool's susceptibility to anchoring bias when symptoms were minimized. The study highlights potential safety concerns as millions use AI for health guidance.

AI transcription tool Otter.ai causes health data breach at Ontario hospital
A former physician at an Ontario hospital installed the Otter.ai transcription tool and gave it access to his digital calendar. Because his personal email was still on a meeting invite list, the AI agent autonomously joined a virtual hepatology round, transcribed it, and emailed the summary and transcript to 65 recipients. The transcript contained sensitive personal health information of seven patients. The hospital reported the breach to the Ontario IPC, took steps to contain it, and is implementing further safeguards.

Clinical algorithm showed racial bias in health care recommendations
In 2019, a study revealed that a clinical algorithm used by many hospitals to identify patients needing extra care was racially biased. Black patients had to be significantly sicker than white patients to be recommended for the same care, due to the algorithm being trained on historical health care spending data that reflected racial disparities. The bias was eventually detected and corrected, but the incident raised concerns about the potential for AI to worsen medical racism.

Google's Med-Gemini AI Hallucinates Non-Existent Body Part in Brain Scan
In a 2024 research paper, Google's Med-Gemini AI model generated a radiology report diagnosing an 'old left basilar ganglia infarct', a non-existent body part conflating the basal ganglia and basilar artery. The error was not caught by Google before publication. After a neurologist flagged the mistake, Google quietly edited a blog post to correct the term, calling it a typo, but the research paper remains unchanged. Experts warn that such hallucinations pose significant risks if doctors fail to notice them in clinical settings.

IBM Watson for Oncology recommended unsafe cancer treatments
Internal IBM documents reveal that its Watson for Oncology system often provided erroneous cancer treatment advice, including 'multiple examples of unsafe and incorrect treatment recommendations'. The problems were attributed to training on a small number of synthetic cases and the expertise of a few specialists rather than real patient data or established guidelines. The system was promoted to hospitals and physicians worldwide. It is unclear whether any patients were harmed as a result.

Microsoft Copilot Audit Log Flaw Left Customers Unaware
A vulnerability in Microsoft 365 Copilot allowed users to access files without the access being recorded in audit logs, potentially enabling malicious insiders to exfiltrate data undetected. The flaw, discovered by Pistachio's CTO, was reported to Microsoft in July 2025 and fixed in August, but Microsoft decided not to issue a CVE or notify customers. The vulnerability could be triggered accidentally, meaning many organisations' audit logs may be incomplete. Microsoft classified the issue as 'important' but faced criticism for its lack of transparency.
